JBL 4344MKII manual Bi-Wiring Connections, Preamp w/Y-corded output Stereo amps

Bi-Wiring Connections

Figures 5 through 8 show two bi-wiring options, single-stereo amplifier and dual-stereo amplifier modes. For passive and bi-wire connections, set the switch to the Normal/Bi-Wire position (Figure 5a).

Important

1. The external “strapping bars” that normally connect the 4344MkII low-frequency and high-frequency terminals must be removed before bi-wiring. To remove the shorting straps, simply loosen and slide the bars off to the side (Figure 8).

2.Never connect two amplifiers to the same loudspeaker without first removing the strapping bars. Operating two amplifier channels without removing the strapping bars can seriously damage your amplifiers!

3.If you have hooked up your 4344MkII loudspeakers in any of the bi-wire configurations indicated, it is not advisable to use additional speakers separately or simultaneously.

4.As with conventional one-amplifier connections, make sure that all speaker cables are the same length.
